This squirrel occurs in central Sulawesi, Indonesia. Records span tropical lowland evergreen to upper montane forest at 350–2,800 m. It is often found high in primary-forest crowns or woody vines, but has also been observed on the ground where the canopy is broken.
The back is dark brown with buff or black highlights. The flanks are paler; the underside ranges from dark gray with silvery highlights to ocherous or pale buff. Buff eye-rings, black ear tufts, and a black-and-buff ringed tail ending in a black tuft are described.
